Resumen
Abstract Phosphine)silver(I) organosulfonate complexes of the type (R3P)AgOS(O)2R’ have been prepared in good yields from the corresponding silver sulfonates and tertiary phosphines in dichloromethane solution [R3 = Ph3, Ph2(2-Py), Me2Ph, with R’ = 4-Me-C6H4; R = Ph, R’ = Et and 2,5-Me2-C6H4]. If ethanol is present in the reaction mixture, the products contain one equivalent of ethanol. The crystal structures of (Ph3P)AgOS(O)2(C6H4-4-Me)(EtOH) (1), and (Me2PhP)AgOS(O)2(C6H4-4- Me) (5) have been determined. Complex 1 is present as a dimer in which the monomeric units feature intermolecular Ag-O donor/acceptor bonding in a four-membered ring. The coordination sphere of the silver atoms is further complemented by an ethanol molecule which is also engaged in hydrogen bonding with one of the sulfonate oxygen atoms. The solvent-free complex 5 is associated into helical chains via Ag-O coordinative bonds which provide the silver atoms with a distorted planar T-shaped coordination.

Resumen
Density functional theory (DFT) calculations were comparatively carried out to reveal the origins of different catalytic performances from phosphine–benzene sulfonate (A, [{P^O}PdMe(L)] (P^O = Κ2-P,O-Ar2PC6H4SO3 with Ar = 2-MeOC6H4)) and α-diimine (B, [{N^N}PdMe(Cl)] (N^N = (ArN=C(Me)-C(Me)=NAr) with Ar = 2,6-iPr2C6H3)) palladium complexes toward the copolymerization of ethylene and methyl vinyl sulfone (MVS). Having achieved agreement between theory and experiment, it was found that the favorable 2,1-selective insertion of MVS into phosphine–sulfonate palladium complex A was due to there being less structural deformations in the catalyst and monomer. Both the MVS and ethylene insertions were calculated, and the former was found to be more favorable for chain initiation and chain propagation. In the case of α-diimine palladium system B, the resulting product of the first MVS insertion was quite stable, and the stronger O-backbiting interaction hampered the insertion of the incoming ethylene molecule. These computational results are expected to provide some hints for the design of transition metal copolymerization catalysts.
